Stephen Joseph Cannell (/ˈkænəl/; February 5, 1941 – September 30, 2010) was an American television producer, writer, novelist, and occasional actor, and the founder of Cannell Entertainment (formerly Stephen J. Cannell Productions) and the Cannell Studios.

After college, Cannell spent four years working with the family business before selling his first script to the Universal series It Takes a Thief in 1968. He was quickly hired by the television production branch of Universal Studios and was soon freelance writing for such other crime shows as Ironside and Columbo. Not long afterward, he received a telephone call from friend Herman Saunders who was the producer on the series Adam-12. They needed a script right away and Saunders asked if Stephen would be interested in writing it. He delivered what they wanted in one day, his first full-time gig, and was soon hired as story editor of Jack Webb's police series Adam-12, then in its fourth season (1971–1972).

He described his early financial arrangements in a 2002 interview, saying that at Universal,

“

I signed a deal as a head writer to make $600 a week. I was the cheapest writer on the lot. It was the lowest deal you could do by Writers Guild standards. But I'd been working for my dad for $7000 a year. I was at Universal for eight years and I never renegotiated my deal but once. It was late in my arrangement with Universal. There was one thing in my deal that my agent had managed to get in there—I had good fees for my pilots. The reason they did it is that they never thought I was going to write a pilot. So they'd give me $70,000 to write a two-hour pilot and a $100,000 production bonus if it ever got made. Then I became the hottest pilot writer at Universal. I was writing two or three pilots a season. I was making $400,000 a year in pilot fees.[2]

”

In 1979, Cannell left Universal and formed his own company, Stephen J. Cannell Productions. For the first few years, Cannell's office was located on the lot at Paramount Studios in Hollywood, though his earlier work at Universal was still distributed by MCA-Universal. Cannell's first series under his new banner was Tenspeed and Brown Shoe, and was soon followed by The Greatest American Hero, The Quest, The A-Team, Hardcastle and McCormick, Riptide, and Hunter. Cannell offices relocated to larger facilities on Hollywood Blvd in 1983.

Cannell also acted occasionally, including a regular supporting role as "Dutch" Dixon on his series Renegade. He also took a turn in an episode of Silk Stalkings, in which the script called for one character to tell him, "You look just like that writer on TV," to which Cannell's character responds, "I get that all the time." He also served as the host of the 1991–92 series Scene of the Crime a mystery anthology series with a repertory cast, 1995–1996 syndicated documentary series U.S. Customs Classified, focusing on the work of the U.S Customs Service.[5] Cannell appeared as himself in the pilot of the ABC show Castle and again in season two. Along with James Patterson, Dennis Lehane, and Michael Connelly, he was one of Castle's poker buddies. In season three, an empty seat at the poker table is described as Cannell's, and remains empty for a full year.

In 1987, and with a favorable exchange rate between the US and Canadian dollars being a win/win for US producers, Cannell decided to shoot his new series Stingray in Toronto. So many producers were shooting in Toronto that no crews were available to man any additional productions. Cannell shot seven episodes of Stingray in Calgary with the remainder being shot in Vancouver. His first series shot there was 21 Jump Street, the highest-rated show of the new Fox network's first season. With more and more series being shot in Vancouver, Cannell said, "We were fighting with everybody for locations and stage space". His solution was to build a new, state-of-the-art facility, "The North Shore Studios" on 13 acres with one hundred thousand feet of office space and seven sound stages. The series 21 Jump Street was soon followed by Wiseguy, The Commish, Booker, Hawkeye, Cobra, The Hat Squad, J.J. Starbuck, Stingray, Street Justice, and Unsub, and a number of television films were also shot in Vancouver by Cannell's production company.

In 1995, New World Communications acquired his Cannell Entertainment production company. Cannell then founded the Cannell Studios.[6] One of the first shows produced by the newly established Cannell Studios was the short-lived but critically acclaimed corporate drama Profit.

Starting in 1995, Cannell turned his attention to writing novels. His first novel, The Plan, was released in 1997 by Avon. As of 2010, he had written 18, 11 of which featured the character of detective Shane Scully of the Los Angeles Police Department. Seven are stand-alone novels. The last in the series, Vigiliante, was released December 2011 by St. Martin's Press.

The 2009 documentary Dislecksia: The Movie features an interview with Cannell, in which he discusses his struggles with dyslexia and how he managed to be such a successful writer despite his difficulties reading. During the interview, he mentions how he used to hire typists to overcome his "spelling problem", as he refers to his dyslexia, but also describes how he feels his condition has enriched his life.[citation needed]

The closing logo of his production company consisted of him typing on an IBM Selectric typewriter in an office/study area, with bookshelves, and awards galore. The camera then pans clockwise from his face to his back. Once the camera is towards Cannell's back, he throws the paper he is typing on over his head. The paper becomes animated on a black background, and floats downwards towards a stack of animated papers below. The paper scoops up the top papers in the stack, and forms a "C", while the text of the company is shown above. Cannell himself stated that the throwing of the paper over his head took many takes as it more often came back and hit him in the face or head. It was updated often, the main differences being Cannell's wardrobe, the addition of new awards in the background. In 1984, the pipe was dropped, because Cannell quit smoking, and (rarely) a new office for the live-action part.[7] And depending on the logo is a list of outfits worn by Cannell:

Cannell married his high school sweetheart, Marcia, in 1964. He "asked her to go steady in the eighth grade".[9] Together they had two daughters, Tawnia and Chelsea, and two sons, Cody and Derek.[9] Derek died in 1981 at age 15 when a sand castle he was building at the beach collapsed and suffocated him.[10] This tragedy had occurred during the filming of the "Captain Bellybuster" episode of The Greatest American Hero. Actor William Katt (an expert musician) wrote a song for Cannell, titled, "Cody the Cowboy". Cannell was so touched by this gift that he named his next son Cody in honor of the song.

Cannell was dyslexic, and was a spokesman on the subject. According to an episode of Paul Harvey's The Rest of the Story, Cannell frequently had to dictate ideas or even complete scripts to a personal secretary. That executive assistant for more than 20 years was Grace Curcio. Following Grace's retirement in 2003, Kathy Ezso became his editor and executive assistant. He discussed his experiences as a dyslexic in the 2009 documentary Dislecksia: The Movie.

Cannell wrote on a typewriter, an IBM Selectric, when not dictating to his executive assistant, and only used a computer for research purposes.[11]

On May 4, 1998, Cannell reacquired his library from Fox.[14] Cannell sold his company in March 1995 to New World Communications for $30 million and News Corporation acquired New World in 1996.[14] However, two of Cannell's series, The A-Team and Hunter are controlled by two other studios: Universal for the former and Columbia for the latter and weren't part of the deal.[14] Also part of the deal, Cannell would pay Fox for international and domestic sales for his series.[14]
